TECHNICAL FIELD

The present invention relates to a binding-off process to preventloosening of loops at an edge of a fabric knitted by a knitting machineon the flat knitting machine comprising at least a pair of front andback needle beds having a number of knitting needles fitted in needlegrooves. The present invention also relates to a knitted fabric thusbound off and to a CAD device used for the binding off process.

BACKGROUND ART

A binding-off process for preventing loosening of loops in the finalcourse (final row of needle loops) at an end of a fabric knitted by aflat knitting machine is known. In the binding-off process, a loop inthe final course of the knitted fabric is laid over the next to form adouble loop and a loop of the next course is formed at the double loop.This knitting is repeated from one end of the fabric to the other endthereof to clear the loops of the final course of the knitted fabricfrom the needles in sequence. When a two-layered fabric comprising frontand back parts is knitted in overlapping relation in back and front andalso the loops in the final course are bound off by using the front andback needle beds, the both fabrics are joined together at an end thereofon the side on which the knitting is finished. For example, when thisbinding-off process is used to join together front and back bodies of asweater along a shoulder line, the need of a sewing process after theknitting can be eliminated.

The applicant previously made the proposals for the binding-off processto prevent loosening of loops while joining together two fabrics knittedin overlapping relation in back and front, like front and back bodies ofa sweater, in Japanese Laid-open (Unexamined) Patent Publications No.Hei 8 (1996)-337946. Japanese Laid-open (Unexamined) Patent PublicationNo. 8 (1996)-337946 discloses the binding-off process wherein after aloop of a front knitted fabric and a loop of a back knitted fabric,placed opposite, are each transferred to the needles on the oppositeneedle beds for a while, the loop of the back knitted fabric is laidover the loop of the front knitted fabric to form a double loop and thena binding-off loop continuous to the double loop is formed. Thisknitting is repeatedly performed to bind off the loops of the front andback knitted fabrics. In this binding-off process, a single row ofbinding-off loops are formed along the joints of the front and backknitted fabrics. It is to be noted that the terminology of “row ofbinding-off loops” used in this specification is intended to mean achain stitch formed in the binding-off process.

In the binding-off process of Japanese Laid-open (Unexamined) PatentPublication No. Hei 8 (1996)-337946, only a single row of binding-offloops are formed and the number of loops in the single row ofbinding-off loops formed in the binding-off process is identical withthe number of wale in the binding-off region.

The present invention relates to a binding-off process to preventloosening of loops at an edge of a fabric knitted and discloses a novelbinding-off process that can reinforce a binding-off section and alsocan suppress elongation of the binding-off section; a bound off fabric;and a CAD device for binding off process.

According to this construction of the presentinvention, the rows of binding-off loops are formed, starting from aplurality of loops in the final course in the binding-off region, andthe knitting that a loop of each row of binding-off loops is laid over aloop in the final course located n-th wale forward of the loop withrespect to the binding-off proceeding direction is repeatedly performedto form n number of rows of binding-off loops. The rows of binding-offloops may be formed in parallel with each other or may be formed insequence in such a manner that after any one of rows of binding-offloops is formed sequentially to the end, the other row of binding-offloops is formed. This binding-off process can provide a plurality ofrows of binding-off loops for the binding-off section and, as a resultof this, the binding-off region can be reinforced and the elongation canbe suppressed. Further, lengths of the rows of binding-off loops can befreely adjusted by adjusting the number of rows of binding-off loopsformed, length of the loop formed, and the number of times to knit therow of binding-off loops formed in the binding-off process.

In the binding-off process mentioned above, the knitted fabric to bebound off may be a two-layered fabric comprising a first knitted fabricknitted in the state of being associated with the first needle bed and asecond knitted fabric knitted in the state of being associated with thesecond needle bed, the first and second knitted fabrics being knitted inan overlapped relation in front and back, and the loops in the finalcourse of the first knitted fabric are retained on the second needle bedand the loops in the final course of the second knitted fabric areretained on the first needle bed, followed by transference of a loop inthe final course of either of the first knitted fabric and the secondknitted fabric to the opposed needle bed so that the loop in the finalcourse of the first knitted fabric and the loop in the final course ofthe second knitted fabric can be overlapped with each other. Accordingto this construction of the present invention, the loops in the finalcourse of either of the first knitted fabric and the second knittedfabric are twisted before they are laid over the loops of the otherknitted fabric and, as a result of this, the first and second knittedfabrics can be joined together without the binding-off section beingprojected.

Also, the present invention provides a knitted fabric knitted and boundoff by using a flat knitting machine comprising (i) at least a pair offirst and second needle beds, which have a number of needles,respectively, and are placed opposite in front and back, between which aneedle bed gap is defined, and at least either of which is movableslidably transversely, and (ii) at least one yarn feeder for feeding ayarn to the needles of the first needle bed and the second needle bed,wherein a plurality of rows of binding-off loops are formed, startingfrom loops in the final course, and loops of the rows of the binding-offloops are laid over loops in the final course located at least two waleaway therefrom, respectively.

BEST MODE FOR CARRYING OUT THE INVENTION

An example of the present invention will be described below withreference to the accompanying drawing figures: 1 showing knittingcourses; 2 showing loops; and 3. A binding-off process of a final courseof a plain knit is taken as an example. FIG. 2 shows the loops in therest of the final course only. Alphabetical letters represent needles onwhich loops were retained in the course 0 of FIG. 1. In the following,the binding-off process of the invention will be explained with anexample wherein a two-bed flat knitting machine comprising a pair offront and back needle beds confronting each other across a needle bedgap and having a number of needles arranged on tops thereof, the backneedle bed being formed to be movable laterally relative to the frontneedle bed, is used in the condition in which all needles are used toknit a fabric, without any empty needles for loop transfer beingarranged between needles for loop forming. The binding-off process ofthe invention may be practically worked by using a four-bed flatknitting machine having a pair of upper front and back needle beds whichare arranged over the lower needle beds and on which loop transfermembers are arrange in the same pitch as the lower needle beds. Also,when the two-bed flat knitting machine is used, a half gauge knittingmay be selected in which front and back knitted fabrics are knitted withalternate needles or with odd needles and even needles, respectively, sothat when the front knitted fabric is knitted, the loops of the backknitted fabric can all be retained by the needles of the back needlebed, while on the other hand, when the back knitted fabric is knitted,the loops of the front knitted fabric can all be retained by the needlesof the front needle bed. In this half gauge knitting, since the frontknitted fabric is associated with the front needle bed and the backknitted fabric is associated with the back needle bed, the empty needlesfor loop transfer can always be reserved on the opposed needle beds.This can allow the front knitted fabric and the back knitted fabric tobe knitted in the form of front stitches and back stitches. The halfgauge knitting may be combined with the racking operation of the frontand back needle beds to provide the lateral shift.

The course 0 of FIG. 1 shows the state before the start of thebinding-off process. The loops of the final course of a plain knittedfabric are retained by the needles B-J of the course 0. The loopsretained by the needles B-J are bound off from the left end toward theright end. This direction of the loops being bound off from left toright is defined as “the binding-off proceeding direction” in thefollowing description. In the course 1, a loop 3 of a first row ofbinding-off loops is formed by feeding a yarn to the needle B of thefront needle bed via a yarn feeder 1, starting from a loop 2 located ata side end of a binding-off region. In the next course 2, the loop 3 istransferred to the needle b of the back needle bed. In the course 3,after the yarn feeder 1 is moved to a location not to cause anobstruction of the knitting, the loop 3 is transferred to the needle Dof the front needle bed and laid over a loop 4 of the final courselocated two wale forward of the loop 2 with respect to the binding-offproceeding direction. In the course 4, a loop 6 of a second row ofbinding-off loops is formed by feeding the yarn to the needle C of thefront needle bed, starting from a loop 5 of the final course. In thecourse 5, the loop 6 is transferred to a needle c of the back needlebed. In the course 6, the loop 6 is transferred to a needle E of thefront needle bed and laid over a loop 7 of the final course located twowale forward of the loop 6 with respect to the binding-off proceedingdirection. Subsequently, the loop to be knitted in each of the courses1-6 is transferred forward with respect to the binding-off proceedingdirection and the newly formed loop of each row of binding-off loops islaid over a loop of the final course to form a double loop. Then, theyarn is fed to that double loop, to form a loop of the next course. Thisknitting is repeatedly performed to bind off the loops in the finalcourse sequentially.

As shown in FIGS. 2 and 3, the two rows of binding-off loops, comprisingthe first row of binding-off loops 11 which is formed in such a mannerthat a loop formed with every other needle B, D, F, . . . is laid overthe next and the second row of binding-off loops 12 which is formed insuch a manner that a loop formed with every other needle C, E, G, . . .is laid over the next, are formed in the knitted fabric bound off in thebonding-off process of the first embodiment. These two rows of thebinding-off loops are formed in parallel and also the number of loops ineach row of binding-off loops is reduced to half as many as the numberof wale in the binding-off region, as compared with the binding-offprocess wherein the number of binding-off loops are formed to beidentical with the number of wale in the binding-off region. In thisembodiment, since the two rows of binding-off loops are formed, thebinding-off section can be reinforced, as compared with the binding-offprocess where only a single row of binding-off loops is formed.

Now, reference will be made of the second embodiment with reference toFIGS. 4-7, taking the process of binding off a shoulder portion of asweater 21 of FIG. 4 as an example. FIG. 4 shows the finished state ofthe sweater 21 to be knitted. The sweater 21 comprises a tubular body 22comprising a front body 22 a and a back body 22 b which are knitted inan overlapped manner in front and back and connected to each other atboth ends thereof, and left and right tubular sleeves 23, 24 joined tothe tubular body 22 from underarms 25 a, 25 b to shoulders 26 ta, 26 b.The knitting of the body 22 starts at its hem 27 and the knitting of thesleeves 23, 24 start at their cuffs 28, 29, and the body 22 and the leftand right sleeves 23, 24 are each knitted in a tubular form up tounderarms 25, separately. The sleeves 23, 24 and the body 22 are joinedtogether at the underarms 25 by knitting the body 22 in the state inwhich the loops in the final course of each sleeve 23, 24 are overlappedwith the loops of the body 22 at their side ends. After completion ofthe joining of the sleeves 23, 24 to the body 22, the front body 22 aand the back body 22 b are joined together at the shoulder 26 in thebinding-off process. As the knitting processes before the start of thebinding-off process of the shoulder portions 26 a, 26 b are alreadyknown, the binding-off process from the point at which the joining ofthe left and right sleeves 23, 24 to the body 22 is ended and thebinding-off process of the shoulder 26 starts will be described in thisembodiment. Also, although the left and right shoulder portions 26 a, 26b sandwiching a collar opening 30 therebetween are both bound off in theactual knitting, only the knitting of the right shoulder portion 26 a ofthe sweater to be bound off is described, for convenience ofexplanation. In this embodiment, the binding-off process starts from anend of the shoulder toward the collar opening 30.

In the course 0 of FIG. 5, the loops of a front shoulder portion of thefront body 22 a, which is formed into the right shoulder portion 26 a inthe sequent binding-off process, are retained by the needles B-G of thefront needle bed and the loops of a back shoulder portion of the backbody 22 b are retained by the needles b-j of the back needle bed. An endof the shoulder is located on the left-hand side as viewed in FIG. 5 andthe needles H-J of the front needle bed are for the collar opening 30.In the course 1, a loop 41 located at a side end of the back shoulderportion is transferred to a position outside of a loop 42 located at aside end of the front shoulder portion retained by the needle B of thefront needle bed. In the course 2, the loop 42 at the side end of thefront shoulder portion is transferred to the needle b of the back needlebed which turned to an empty needle. In the course 3, the loop 41located at the side end of the back shoulder portion is transferred backto the needle b of the back needle bed and laid over the loop 42 at theside end of the front shoulder portion to form a double loop. In thecourse 4, a loop 44 of a first row of binding-off loops is formed byfeeding a yarn to the needle b via a yarn feeder 43, starting from thedouble loop formed by the loops at the side ends of the front and backshoulder points. In the course 5, after the yarn feeder 43 is moved to alocation not to cause an obstruction of the knitting, the newly formedloop 44 is transferred to the needle D of the front needle bed and laidover a loop 45 of the front shoulder portion. In the course 6, a loop 46retained by the needle c located forward of the loop 41 transferred inthe course 1 with respect to the binding-off process proceedingdirection is transferred to the needle B of the front needle bed. In thecourse 7, a loop 47 retained by the needle C of the front needle bed istransferred to the empty needle c of the back needle bed. In the course8, the loop 46 of the beck shoulder portion as was transferred to theneedle B of the front needle bed is transferred to the needle c and islaid over the loop 47 of the front shoulder portion to form a doubleloop thereat. In the course 9, a loop 48 of a second row of binding-offloops is formed by feeding the yarn to the needle c via the yarn feeder44, starting from that double loop. In the course 10, after the yarnfeeder 44 is moved, the newly formed loop 48 is transferred to theneedle E of the front needle bed and laid over a loop 49 of thebinding-off loops in the final course. Subsequently, this knitting isrepeatedly performed until the loops are all bound off, while the loopsto be knitted in each of the courses 1-10 are sequentially transferredforward with respect to the binding-off proceeding direction.

The knitted fabric bound off in the binding-off process of the secondembodiment is shown in FIG. 7. The newly formed loop 44 on the doubleloop, which is formed from the loop 42 retained by the needle B and theloop 41 retained by the needle b in the course 0, is laid over the loops45, 51 retained by the needles D and d, respectively. Likewise, thenewly formed loop 48 on the double loop, which is formed from the loops46, 47 retained by the needles C and c, respectively, is laid over theloops 49, 50 retained by the needles E and e, respectively. In theknitted fabric subjected to the binding-off process of the secondembodiment, two rows of binding-off loops are formed, comprising a firstrow of binding-off loops 52 which is formed by laying a loop formed withevery other needle B b, D d, F f, . . . over the next and a second rowof binding-off loops 53 which is formed by laying a loop formed withevery other needle C c, E e, G g, . . . over the next. The first row ofbinding-off loops 52 and the second row of binding-off loops 53 are bothformed to have the number of loops half of the number of wale in thebinding-off region. In the second embodiment, the loops in the finalcourse of the front shoulder portion are retained on the back needle bedand the loops in the final course of the back shoulder portion areretained on the first needle bed, followed by transference of a loop inthe final course of the front shoulder portion to the opposed needle bedso that the loop in the final course of the front shoulder portion andthe loop in the final course of the back shoulder portion can beoverlapped with each other. As a result of this, the loops in the finalcourse of the back shoulder portion are twisted before they are laidover the loops of the front shoulder portion. As a result of this, thebinding-off section can be prevented from being projected. In addition,since the loops 44, 48 of the row of binding-off loops go into hidingunder the loops of the other row of binding-off loops and the loops inthe final course 51, 52, 50, 49, the loops of the rows of binding-offloops different in orientation of wale from each other are preventedfrom coming out to the front side of the knitted fabric. As a result ofthis, a good-looking line of loops can be formed. As the details on thereason that the binding-off section is prevented from being projectedand on the reason that the loops of the row of binding-off loops go intohiding under the knitted fabric are discussed in Japanese Laid-open(Unexamined) Patent Publication No. Hei 8(1996)-337946, the descriptionthereon is omitted herein. As mentioned above, in the second embodiment,two rows of binding-off loops are formed and accordingly the number ofloops in each row of binding-off loops is reduced to half, as comparedwith the binding-off process wherein the number of binding-off loops ineach row of binding-off loops are formed to be identical with the numberof wale in the binding-off region. Hence, even when a line ofbonding-off loops extends horizontally, like the sweater 21 of FIG. 4,so that there is no course difference between the loops in the finalcourse connected by the loops of the rows of binding-off loops, theloops of the rows of binding-off loops can be prevented from becominglarger than the space between the adjoining loops of the final course byincreasing the number of loops in the row of binding-off loops. As aresult of this, the row of binding-off loops can be prevented from beingloosened to make the binding-off section odd-shaped.

As mentioned above, according to the present invention, length of therow of binding-off loops can be freely adjusted by adjusting the numberof rows of binding-off loops formed, length of the loop formed, and thenumber of times to knit the row of binding-off loops formed in thebinding-off process. For example, as the number of rows of binding-offloops increase, the reinforcement of the binding-off section increase.When the number of times to knit the row of binding-off loops formed inthe binding-off process is reduced to reduce the number of loops of therow of binding-off loops, the knitted fabric whose knitting width isshrunk in the binding-off section can be knitted. Although theembodiments have been described above, taking the binding-off processfor the section where the line of binding-off loops extends horizontallyas an example, the binding-off process of the present invention may beapplied to other sections as well, without limited to the section wherethe line of binding-off loops extending horizontally. Also, although thebinding-off process wherein two rows of binding-off loops are formed hasbeen described in the embodiments above, three or more rows ofbinding-off loops may be formed, depending on the material quality ofthe knitting yarn used for the knitting and on the stitch quality ordensity of the loop formed. Supposing that the loops in the row ofbinding-off loops and the loops in the final course are overlapped witheach other in the proportion of one to one, the number of loops per rowof binding-off loops can be reduced by increasing the number of rows ofbinding-off loops. In the case where three rows of binding-off loops areformed, a loop in the row of binding-off loops is laid over a loop inthe final course located three wale forward of that loop with respect tothe binding-off proceeding direction. In the case where four rows ofbinding-off loops are formed, a loop in the row of binding-off loops islaid over a loop in the final course located four wale forward of thatloop. Also, although the embodiments wherein whenever one loop of therow of binding-off loops is formed, the one loop is laid over a loop inthe final course have been described above, whenever two or more loopsof the row of binding-off loops are formed, those two loops may be laidover loops in the final course. In addition, a plurality of yarn feedersmay be used in the binding-off process so that the individual rows ofbinding-off loops can be formed by their respective yarn feeders.Further, although the first row of binding-off loops and the second rowof binding off loops are formed in parallel in the embodiments mentionedabove, one of the first and second rows of binding-off loops may beformed, first, and, then, the other of the first and second rows ofbinding-off loops may be formed. Furthermore, the binding-off proceedingdirection may be reversed so that for example the first row ofbinding-off loops may be formed sequentially in the rightward directionfrom the left end of the binding-off region to the right end thereof,first, and, then, the second row of binding-off loops may be formedsequentially in the leftward direction from the right end of thebinding-off region to the left end thereof.

The binding-off process mentioned above is carried out by knittingcommands stored in a disc and the like being read by a computer built inthe flat knitting machine. The computer of the flat knitting machineinterprets the knitting commands and drives mechanisms of the flatknitting machine in a controllably manner. The principal knittingprocesses including the bonding-off process are stored in the form ofsubroutines in a CAD device for designing a knitted fabric. This type ofCAD device includes the computer and output equipment so that theknitting commands can be written on the disc and the like. The CADdevice stores the principal knitting commands in the form ofsubroutines. The subroutines associated with respective parts of thefabric designed by a user are properly combined with each other,followed by the output of the knitting commands. The knitting commandsinclude the command for the flat knitting machine having the computerbuilt-in to knit the fabric in accordance with the knitting commands.The flat knitting machine is driven under control of the built-incomputer, while also the knitting commands stored in the disc and thelike are read by the built-in computer and are interpreted by the CADdevice, to reproduce a design picture of the fabric designed on the CADdevice by the user.
